How to find out which X11 driver system is using?

For my chip openchrome is the best driver but I suspect that system is not using it. I just need at least 2D acceleration.

How can I check?

Here is it what I found from cat /var/log/Xorg.7.log | grep driver:

[    54.147]    X.Org XInput driver : 12.3
[    55.167] (==) Matched openchrome as autoconfigured driver 0

From what I have got it's not using openchrome.

Here's lspci | grep VGA:

(This is a Thin Client.)

And this is output of grep -E '(\(WW|\(EE)' /var/log/Xorg.7.log:

  • Does lsmod | grep openchrome show anything?

  • Based on the output it is using openchrome driver but cannot set the 1280x1024 mode

  • isn't it using DRI instead of openchrome?

  • @casey_miller DRI is an extension which may or may not be supported by the driver

To answer your original question, yes you are using the OpenChrome driver. It just unfortunately has minimal support for your chipset, even less if it isn't the most recent. As of now you should be able to get Basic 2D, and whatever 2D acceleration was supported for your chipset. Its up to you to say if its 'good enough', or worth changing to something better.

Openchrome has gone through a lot of improvement from after 09`, and distro's always end up many releases outdated. Chrome 9 support has improved in recent OpenChrome releases, which should provide better performance/stability/features.

In addition a proprietary driver exists for Chrome 9 HC3, but not every distro has a package available. This is the better option for an outdated distro. Basically which way to go depends on your distro's release, and/or if you compiled yourself.

I might be able to direct you to a easy upgrade option, need distro version to know. If you don't know it helps to Identify LSB Release

## outdated distro's might not support this command    
lsb_release -a

## Most Distro's will display release, in an /etc file.
cat /etc/*release

Check for Video Overlay

## Still verify Xv works, whenever you get X running again.

  • I have included the output of the last two commands. I couldn't run glxinfo (doesn't exist, figuring out how to install) and xvinfo (I do have it but getting: xvinfo: Unable to open display) (I don't have window manager)

  • @casey_miller: I updated my answer to reflect your question. The ball is now in your court. Accept answer when you know its good enough, or I could always help you upgrade. Jan 18, 2012 at 9:46
  • the fun thing is that it can play HD video full screen with current hardware and driver (btw the version is Package: xserver-xorg-video-openchrome (1:0.2.904+svn920-1) I am running 11.10. In packages list of 12.04 version the version of openchrome is the same

  • that version is fairly recent, you don't need to change if it's working. Your distro is too recent to get benefits from the closed driver, so your best off staying where you are. Jan 18, 2012 at 11:45
  • The problem hasn't gone but I think this answer can be accepted. And for further actions I can create other questions. Thanks!

Depending on which system you are on the location of the X log may be different but on Linux: /var/log/Xorg.0.log. If you search for the word driver you will be able to see lines like this:

[    34.252] (==) Matched fglrx as autoconfigured driver 0
[    34.252] (==) Matched ati as autoconfigured driver 1
[    34.252] (==) Matched vesa as autoconfigured driver 2
[    34.252] (==) Matched fbdev as autoconfigured driver 3

This means that it will use one of these drivers for it.

You can also take a look at:


search for the Device section which will tell you which driver it will use. You can also try doing:

sudo X -configure

to create the /etc/X11/xorg.conf

Based on your further comments you should look at this page for more guidance. You may have to play with options like for 10.04 release to see if you can get it to work.

  • Here is what I got from /var/log/Xorg.7.log (it's 7 not 0 for some reason). See updated question.

  • @Karlson How can you tell he's using Ubuntu? Jan 18, 2012 at 17:44
  • @MichaelMrozek In the comments in the answer below OP mentions running version 11.10 and 12.04. 11.10 is the latest Ubuntu release and 12.04 is currently being tested. And Ubuntu's versioning scheme is pretty unique.
